Introducing a Linear Gamma Variate Fit to Measure Pulmonary Perfusion with Electrical Impedance Tomography

Applications of Electrical Impedance Tomography in Neurology

Introduction: Electrical impedance tomography (EIT) is a non-invasive technique utilized in various medical applications, including brain imaging and other neurological diseases. Recognizing the physiological and anatomical characteristics of organs based on their electrical properties is one of the main applications of EIT, as each variety of tissue structure has its own electrical characteris...

Addendum to ‘Electrical impedance tomography’

We present some additional references and clarifying statements to the topical review ‘Electrical impedance tomography’ (Borcea L 2002 Inverse Problems 18 R99–136). In this addendum to ‘Electrical impedance tomography’, the author would like to make some clarifying statements regarding section 7.1.2 and to direct the reader to additional references relating to sections 4.3 and 6.1. • The idea o...

From Electrical Impedance Tomography to Network Tomography

Hyperoxia affects the regional pulmonary ventilation/perfusion ratio: an electrical impedance tomography study.

BACKGROUND The way in which hyperoxia affects pulmonary ventilation and perfusion is not fully understood. We investigated how an increase in oxygen partial pressure in healthy young volunteers affects pulmonary ventilation and perfusion measured by thoracic electrical impedance tomography (EIT). METHODS Twelve semi-supine healthy male volunteers aged 21-36 years were studied while breathing ...

Pulmonary ventilation and perfusion assessed by electrical impedance tomography Experimental studies in pigs

Pulmonary ventilation and perfusion and ventilation/perfusion (V/Q) matching determine gas exchange in every lung unit in the healthy state and in the pathologically altered lung. Mismatch of V and Q lead to hypoxaemia and hypercapnia and monitoring of V/Q relations are thus important in critical illness. This thesis focuses on electrical impedance tomography (EIT) to monitor pulmonary perfusio...
